Abstract: A secondary satellite radio or broadcast channel is used to broadcast advertisement clips (e.g., audio clips) to a receiver for subsequent decoding and playback. The receiver is configured for different tiers of service, e.g., one that delivers substantially advertising-free content and another that delivers content that includes more significant amounts of advertising. The content delivered to both is the same content; however, for the service tier that includes more advertising, the advertisements broadcast on the secondary channel are interleaved into the content, preferably in such a way that the continuity of the content being delivered is not compromised.

Abstract translation: 辅助卫星广播或广播频道用于将广播片段（例如，音频剪辑）广播到接收机以用于随后的解码和重放。 接收器被配置用于不同的服务层，例如提供实质上无广告的内容的接收器，另一个传送包括更多大量广告的内容。 提供给两者的内容是相同的内容; 然而，对于包括更多广告的服务层，在辅助信道上广播的广告被交织到内容中，优选地以这样一种方式使得被传递的内容的连续性不受影响。

Abstract: The present invention I related to a contents provider supplies encoded contents to a transmitting station, and broadcasts the encoded contents via a satellite. At a gas station inside a service area of the satellite, a base station to receive the contents from the satellite is disposed. The contents provider transmits to each base station decoding keys to decode the transmitted contents via the Internet. The base station relates the received contents to the decoding keys to store in a large capacity memory. When a vehicle stops by at the gas station, a vehicle-mounted apparatus communicates with the base station so as to download the contents, accumulate in a memory, and reproduce. This enables digital contents to be distributed to a mobile body with small-scale equipment.

Abstract: A data transmission device transmits a data broadcast using a narrow unused broadcasting band in a digital broadcast, and to record the data broadcast, which has been received, on a receiving side so that the receiving side can play back the data broadcast after a data stream is totally recorded. The transmission device generates a first data stream, which is recorded on a recording medium on a receiving side, and a second data stream including audio and video data, which is transmitted as a broadcasting program. The transmission device multiplexes the first and the second data streams and then transmits the multiplexed data stream. The transmission of the multiplexed data stream is controlled so that a transmission rate for the multiplexed data stream does not exceed the maximum transmission rate, and so that a transmission rate for the first data stream becomes lower than that for the second data stream. A receiving device records the first data stream on the recording medium, and permits the first data stream to be played back for use after the transmission completes.

Abstract: Connected to a satellite earth station for transmitting a broadcast signal to a communication satellite, a data (distribution) center publishes contents of stored information on a home page (HP) of the Internet to submit retrieval of users. When each user determines date to be gotten by retrieving on HP, the user transmits a request signal to the date center via a ground Internet or the communication satellite. Responsive to the request signal, the date center returns a reservation signal including a group address and a distribution scheduled time instant to a request source via the communication satellite. A user's terminal receives date with the group address at a reserved time instant, deciphers the date using a key given from the date center separately, and stores deciphered date in a memory thereof.

Abstract: A microcontroller or microprocessor-controlled broadcast receiver embedded in an external peripheral with a digital communications interface. In one embodiment, a microprocessor-controlled broadcast receiver is embedded in the housing of an external computer peripheral. The external computer peripheral is connected to a personal computer (PC) via a digital communications link such as USB (universal serial bus). Control data is relayed from the personal computer to the broadcast receiver in the external computer peripheral via the digital communications link. Audio signals received by the broadcast receiver in the external computer peripheral may also be relayed to the personal computer via the digital communications link or via an analog interface for recording storage, or manipulation by the personal computer. The broadcast receiver may also receive data signals in addition to audio signals (datacasting). The data or audio signals or both may be encrypted.

Abstract: A digital broadcast transmission system comprises a plurality of spaced transmitters (6). Each transmitter (6) receives signals for transmission from a master transmitter (2), e.g. on a satellite, along with a reference frequency (F.sub.REF). The reference frequency is used to generate the transmission frequency at each spaced transmitter. At a receiver (12), conversion means can be used, to enable signals from the master transmitter (2) and from the other transmitter(s) to be received. A preferred application is digital audio broadcasting (DAB). Specifically, the present invention is useful in connection with Coded Orthogonal Frequency Division Multiplex (COFDM) modulation.
